Fig 5. In situ identification of plk1-expressing cells in samples of Taenia crassiceps cyst.

HE staining (A) and ISH on Taenia crassiceps cyst (B) were also performed; positive cells were observed in the region of the "buds" formation (black arrows) and along the bladder wall of these structures (arrowheads). A higher magnification image is inserted. A sense probe (C) was used as a negative control. B: Bud.
